Your Public IPv4 Address
The easiest way to find your public IP address is using the web. You can navigate to a website, such as whatismyip.com, or simply search, "What is my IP address" in a search engine such as Google to produce the result.

Your Private IPv4 Address
To find your private IP address, you can use a terminal. Depending on which OS (Operating System) you are running, the command to determine your IP address will differ. On a Linux or Mac, type in ifconfig
, whereas on a Windows computer, type in ipconfig
to find your IP address. The result may look like so,
Ethernet adapter Ethernet:
Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::14a5:92a8:6620:114a%4
IPv4 Address. . . . . . . . . . . : 192.168.50.197
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.50.1
Often, running this command will return not one, but a number of network interfaces. Ethernet interfaces will be labelled eth0
, eth1
, etc., while Wi-Fi interfaces are often labelled wlan0
, wlan1
, on so on. A Mac may return an especially large number of network interfaces, as it uses a number of loopback interfaces (interfaces that the OS uses to communicate with itself).

QUESTION:
Do you have IPv6 enabled?
ANSWER:
If you do - that's great, your ISP is on top of things! If you don't - not to worry, you're likely to have it soon.
